As scientists strive to understand and predict the effects of climate change on the Northwest’s fish, wildlife, hydrology, and ecosystem services, a foundational piece of knowledge they require is how the climate, the water cycle, and the vegetation will change in the future. Funded in part by the Northwest Climate Science Center, this project integrates, for the first time, state-of-the-science predictive modeling of these different attributes of the future environment in the Northwest, and will provide coherence and guidance for many scientific studies seeking to work out the details of how climate change will affect various plant and animal species and other aspects of ecosystem services. This project has evaluated and downscaled global climate models (from the Coupled Model Intercomparison Project phase 5, CMIP5), examined projections from these models and also from regional climate models, and improved and applied hydrologic and vegetation models.
